Detailed description of the Invention
The present invention is the method for a kind of preparation as the light damp PEIT polymkeric substance that fills hot vessel, bottle, thick sheet, film, fiber, wire rod, optical goods and other goods.Color and luster is used the Hunter value representation usually, bright or dark (" L ") of its counter sample, red green target colour (" a* "), the colour of champac colour code (" b* ").Usually needing " L " of preparation polymkeric substance is 80-100, preferred 90-100.Similarly, for low color polymers, " a* " and " b* " be preferably approximately-2.0-approximately+2.0, more preferably approximately-1.0-approximately+1.0, these values are measured according to methods described herein.For PEIT, found by controlling the important technical parameter of described each step of method, particularly temperature and pressure, need not to add the additive of proofreading and correct color and luster and just can reach these purposes.
In order to prepare light damp PEIT, it is also important that the impurity that adds lustre to of eliminating or being present in the monomeric diol to the major general reduces to minimum.Preferably in the ultraviolet light absorption rate of 220nm place ethylene glycol and Isosorbide less than 0.20, be more preferably less than 0.10.
The selection of polycondensation catalyst also influences the color and luster of final polymkeric substance.The catalyzer that is fit to comprises oxide compound and the Ti (OR) of oxide compound, Sb (III) and the Ge (IV) of the acetate of salt, Co (II) and Sb (III) of Sb (II I) or Ti (IV) and other alkanoates, Sb (III)
4, wherein R is the alkyl of 2-12 carbon atom.Also can use the oxide compound that dissolves in dibasic alcohol of these metal-salts.Oxide compound such as the GeO of preferred Ge
2Usually the consumption of polycondensation catalyst is preferably the about 300ppm of about 10-, by weight.More particularly, the molar ratio of catalyzer and terephthalic acid or its ester is about 1: about 1: 7300 of 1000-, about 1: 4400 of preferably approximately 1: 2200-.
The raise Tg (for PET) of final PEIT polymkeric substance of the existence of isosorbide monomer can reduce Tg yet introduce DEG in the polymkeric substance.When having used terephthalic acid in the described polymerization process, can generate DEG and also be incorporated in the polymkeric substance subsequently.Purposes and described polymerization process for the low DEG of needs use terephthalic acid, can add suitable alkali and the ratio of ethylene glycol in the initial esterification reaction and diacid is reduced to minimum.Found that suitable alkali and monomer are added reactor has together suppressed that DEG generates in the PEIT polymkeric substance.The alkali that is fit to comprises sodium acetate, sodium hydroxide and tetramethylammonium hydroxide (TMAH).The significant quantity of alkali is the about 300ppm of about 10-, based on terephthalic acid.In the embodiment of this paper, when described method has been used terephthalic acid, germanium oxide (GeO
2) and the combination of TMAH obtain the very polymkeric substance of light color and low DEG content.For some purposes that needs high Tg value, described DEG content is preferably and is less than about 1.5% mole, more preferably is less than about 1.0% mole.
Polymerization process of the present invention is the polycondensation method of ethylene glycol, Isosorbide and terephthalic acid or its alkyl ester.The terephthalate that is fit to that is used for the inventive method comprises terephthalic acid list and dialkyl, and wherein said alkyl is selected from C
1-C
6Alkyl.Preferred terephthalate is a dimethyl terephthalate (DMT).The molar ratio of glycol (ethylene glycol and Isosorbide) and terephthalic acid (or its ester) is about 1.05: about 1.3: 1 of 1-, the molar ratio of ethylene glycol and Isosorbide are about 1.2: about 24: 1 of 1-, preferably approximately 6: 1-18: 1.
Described polymerization process can be intermittently, semicontinuous or continuous mode carries out.Best described method is carried out in the reactor that distillation tower and agitator or other whipping devices are housed.The volatile products (water and/or alkanol) of described distillation tower separating reaction from return volatile reactants (for example ethylene glycol and Isosorbide).Using distillation tower to make can operate under the low molar ratio of ethylene glycol and terephthalic acid, and this is used for suppressing the generation of DEG.When having used terephthalic acid in the described polymerization process, volatile reaction product is a water; When having used ester such as dimethyl terephthalate (DMT), volatile reaction product is corresponding alkanol (a for example methyl alcohol), also with a spot of water.
Catalyzer that reactant (terephthalic acid or its ester, ethylene glycol and Isosorbide) and other are optional and additive are packed in the reactor, if necessary, reactor are purged to remove the oxygen of trace.Rare gas element such as nitrogen can be used for this purpose.At pressure is that the reacting by heating thing begins polyreaction in the inert atmosphere of the about 60psig of about 0-, simultaneously by dephlegmate and/or alkanol and other volatile byproducts.When using terephthalic acid, temperature is increased to about 220 ℃ at first, and when using terephthalate, temperature is increased to about 180 ℃ at first, slowly is increased to outlet temperature 230-255 ℃ then.In about 1-8 hour, most of water and/or alkanol have been removed.
The efficient of distillation tower and the ratio of ethylene glycol and Isosorbide are depended in the selection of pressure.If ratio is 9 or lower, then can approximately operate under the Opsig usually.If ratio is higher, then separate easier water that ethylene glycol is formed from the reaction of ethylene glycol, Isosorbide and terephthalic acid or its ester of pressurize and/or the alkanol.But pressurize makes that also to remove the volatility impurity that adds lustre to by distillation more difficult, therefore preferably operates under the needed minimum pressure of acceptable low ethylene glycol losses in keeping distillate usually.
The boiling point that should be pointed out that described reaction mixture is the function that described mixture is formed, the function of the ratio of more specifically say so Isosorbide and ethylene glycol.Ratio height, the high temperature of the then elevation of boiling point, and described reaction mixture cause speed of reaction to improve and follow the increase of water and/or alkanol product.On the contrary, when the ratio of Isosorbide and ethylene glycol hanged down, the boiling point of described reaction mixture was lower, caused described reaction mixture temperature lower.The entire effect of the low ratio of Isosorbide and ethylene glycol is that esterification carries out slowlyer, and the percentage ratio of ethylene glycol increases in distillate.
When described reaction mixture temperature raises, for example when 220 ℃ (for terephthalic acids) or 180 ℃ (for terephthalate) are increased to 230-255 ℃, at least 80%, the water and/or the alkanol of preferred at least 90% reaction are removed.The top temperature of described reaction mixture is limited in 255 ℃ of generations that at utmost reduced the by product that adds lustre to.Preferred this step also can optionally remove anhydrate and/or alkanol and temperature and pressure condition with the ethylene glycol Returning reactor under carry out.Preferred described distillate comprises the ethylene glycol that is less than about 5% weight and less than the Isosorbide of about 1% weight.This can reach by adjusting described reaction mixture temperature, so that distillation tower overhead vapor (overhead vapours) temperature is not higher than the boiling point (if described method is used terephthalic acid) of water under the reactor pressure or the boiling point (if described method is used terephthalate) of alkanol.If the overhead vapours temperature has surpassed the boiling point of water (or alkanol), then reduce described reaction mixture temperature, there is not distillate to distillate, be lower than the boiling point of water under the reactor pressure (or alkanol) up to the overhead vapours temperature.
When reaching 230-255 ℃ and overhead vapours temperature, described reaction mixture temperature drops to the about 2-20 of boiling point ℃ that is lower than water under the reactor pressure or alkanol, during 5 ℃ of preferably approximatelies, reactor pressure is with about 0.5-5psi/min, and the speed of preferably approximately 1-2psi/min drops to about normal atmosphere.When reactor pressure descends, will from reactor, distill out extra water or alkanol.The iptimum speed that pressure descends is determined by the overhead vapours temperature.If when the overhead vapours temperature surpassed the boiling point of water under the reactor pressure or alkanol, the pressure fall off rate reduced.On the contrary, if when the overhead vapours temperature is lower than the boiling point of water under the reactor pressure or alkanol, the pressure fall off rate improves.If reactor when normal atmosphere, remove anhydrate or the total amount of alkanol less than aequum, pressure can be reduced to about 80mmHg (for terephthalic acid) or approximately 125mmHg (for dimethyl terephthalate (DMT)) further promote esterification.For other terephthalate, pressure can be reduced to the pressure of alkanol boils under the room temperature.Usually, before the next step that continues described synthetic method, preferably remove at least 90% volatile reaction product (water and/or alkanol) altogether.
The next step of polymerization process is polycondensation, and the reaction of ester and oligopolymer forms polymkeric substance in polycondensation, removes residual ethylene glycol, Isosorbide and water and/or alkanol simultaneously.If polycondensation catalyst not and monomer add together, then can add together with other desired additives such as infrared absorbent, dyestuff, pigment, UV light stabilizing agent and other thermal stabilization additives in that this step is optional.
Can add and be selected from red, orange, yellow, blue, green, indigo and purple color and luster correction additives.The example of these dyestuffs or pigment comprises cobaltous acetate, HS-325
Red BB, HS-510
Blue 2B,
BlueR, and
RSB violet is particularly useful for the b* value that reduces the PEIT polymkeric substance.Then reactor pressure is reduced to about 0.25-2mmHg, preferably approximately 0.25-1mmHg.When reducing pressure, described reaction mixture temperature is increased to 260-275 ℃.Described reaction mixture is kept about 1-4 hour to form required PEIT polymkeric substance under this temperature and pressure.Time is at high temperature farthest shortened the formation that helps to reduce color and luster in the PEIT polymkeric substance.
Described polymkeric substance can be shifted out from reactor and for example make section bar, granulation or thinly slice and separate with any various common process.By described melt polymerization process, the limiting viscosity that obtains (IV) is 0.5dl/g or higher.Can further improve IV by the solid state polymerization of described separation polymkeric substance.
Processing condition according to the rules obtain having the PEIT polymer product of light pool and low DEG content, can be used for filling hot vessel, bottle, fiber, optical goods, film and thick sheet.PEIT of the present invention also can be used for preparing blend polymer and polymer alloy.
